For the rest, names of places prove that the Norwegians had also settled themselves along the coast to the south of the Oykill. On the narrow naze called Tarbet Ness, between Dornoch and Cromarty Firths, are the villages of Arboll and Wanby, as well as the town of Tain, whose Gaelic name, “Bailed Dhuich” (or St. Duthus’ Town), shows at once that “Tain” must be of foreign origin. Tain is, moreover, a corruption of “Þing,” a _Thing_; and in like manner the somewhat considerable town of Dingwall, at the extremity of Cromarty Firth, was originally called “Þingavöllr,” or _Thingwalla_; whence the remarkable fact is evident, that the Norwegians were once sufficiently numerous in these districts to have both an inferior _Thing_ (Tain) and a superior one (Dingwall). Dingwall, like Tain, besides its original Norwegian name, has also the Gaelic one of Inverphaeron. As the Norwegians, therefore, must have permanently possessed considerable tracts in these districts, it is clear that their settlements on the east coast of Scotland must have extended quite down to Inverness-shire and Moray. The before-mentioned stronghold of Burghead in Moray, which the Northmen maintained to the last extremity, lies pretty close to the east of Cromarty Firth, the inlet to Dingwall. As the Norwegian language and other Norwegian characteristics have given way to the Gaelic tongue, manners, and customs, in the former Norwegian districts on the north coast of Scotland, from Clyth Ness in Caithness to Dingwall on the Firth of Cromarty, we can scarcely be surprised that the north coast of Sutherland, whose rocks and heaths offered much fewer allurements to the Norwegians than the fertile valleys and plains of the east coast, and which were therefore far less colonized by them, should have preserved distinct traces of these foreign conquerors only in a few names of places. A remarkable instance of the Gaelic language having expelled the Norwegian is to be found immediately on the borders of Caithness, in the valley of Halladale. In a river there are two waterfalls, of which the uppermost is called Forsinard, and the lower one Forsindin. In both these names the Norwegian “Fors” is not to be mistaken; but Gaelic terminations have in later times been added by the Gaels, so that Forsinard now signifies the upper Fors, and Forsindin the under, or lower, Fors. Halladale is likewise frequently called by the additional Gaelic name of Strath—“Strath Halladale.”
